Cadillac Model M. In 1907, Cadillac offered two distinct touring car body styles for the Model M series: the elegant Victoria Light Touring Car and this "Straight" Light Touring Car. Both were powered by the single-cylinder Cadillac engine and priced at $950, or $1,025 with a top. In 1908, three Model M Runabouts similar to this touring car were randomly selected to prove that the precision manufacturing methods employed by Cadillac guaranteed complete interchangeability of parts.

1907年，凯迪拉克品牌为旗下的M系列车型提供了两种不同的车身设计：优雅风格的四轮折蓬式车型和直线型敞蓬车，这两种车型都配备了凯迪拉克的单缸发动机，售价从 950美元到1025美元。1908年，和这款四座敞蓬车相似的三款M型小型单座敞篷车的出现充分证明，凯迪拉克品牌的精密制造工艺和标准化的零部件生产，确保了汽车零部件可在不同车型之间交替使用。

Initially, one specimen is tested at an irradiance of 25kW/m in the presence of a pilot flame and one specimen is tested at an irradiance of 25kW/m in the absence of a pilot flame to determine the mode which gives the quickest rate of smoke production.

首先，把一个样品用带有引燃火焰的25KW/m 的辐射进行测试，另外再用不带引燃火焰的25KW/m 的辐射进行测试，并用此来确定最快产生烟的一种方法。

In this study, a commercial CAD/CAM Software is used to plan and generate the multi-axis tool path, and a table rotating/tilting type five-axis machining center is used to perform the experimental machining operation. The material of the die studied is NAK 80 die tool steel, and the geometries are modeled as concave and convex spherical surfaces. Milling parameters considered are spindle speed, feed rate, and different types of cutting tool path. The experimental results show that the surface roughness for concave spherical surface is about 0.247 μm and roundness is about 0.0283 mm and the surface roughness for convex spherical surface is about 0.250 μm and spherical roundness is about 0.0551 mm under the cutting conditions mentioned in this study.
